WATER-PROPELLER.

To all whom it may concern:

Be it known that we, THOMAS SALVESON and LETHA E. SALVESON, citizens of the United States, residing at Birney, in the county of Rosebud and State of Montana, have invented certain new and useful Improvements in Water-Propellers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide an improved water propeller especially designed for use in connection with irrigating systems and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure l is a front end elevation of our invention; Fig. 2 is a view partly in longitudinal vertical sec tion, taken on the line 0& m of Fig. 1, and partly in side elevation; and Fig. 3 is an edge elevation of the improved propeller with some parts sectioned on the line m w of Fig. 1.

The numeral 1 indicates a casing which, as shown, is in the form of a horizontally extended cylinder open at both ends and mounted on the bed of a stream, lake or other body of water and held, by any suitable means, not shown, in a position to be submerged in the water.

Extending axially into the cylinder 1 is a shaft 2 journaled, at its rear end portion, in a pair of depending brackets 3 secured to the cylinder 1. Rigidly secured to the for ward end portion of the shaft 2 is the improved water propeller comprising a vertically extended disk-like web 1 having formed therein a pair of diametrically opposite water passages 5. Oblique pockets 6 and 7 are formed on opposite sides of the web 1 and extend in opposite directions circumferentially of said web. The pockets 6 are Specification of Letters Patent.

arranged to deliver water to the passage 5, and the pockets 7 direct the water therefrom into the cylinder 1. The pockets 6 will scoop the water up and the pockets 7 will produce a sort of suction that draws the water through the passages 5 and into the cylinder 1. By extending the pockets 7 completely over and considerably to one side of the passages 5, said passages are relieved from direct pressure of the water from Within the cylinder 1. The web 4 extends substantially in the same plane as the outer end of the cylinder 1 and is provided with an inturned peripheral flange 8 that works close to the inner face of the cylinder 1.

Rotary motion is imparted to the improved propeller in the direction of the arrow marked thereon in Fig. 1 by means of a power driven shaft 9 journaled in bearings 10 secured to and projecting above the cylinder 1. A sprocket chain 11 runs over alined relatively large and small sprocket Wheels 12 and 13 keyed, respectively, to the shafts 9 and 2. Any suitable means, not shown, may be provided for driving the shaft 9. The rear end of the cylinder 1 opens into a standpipe 14. In actual practice, a check valve will be provided to prevent the return of water from the standpipe to the pump cylinder.

What we claim is:

1. The combination with a casing, of a water propellerjournaled in said casing and comprising a disk-like web having a passage therethrough, and pockets on opposite sides of said web extending in opposite directions circumferentially of said web, said pockets arranged one to deliver water to said Web passage and the other to direct the water from said passage.

2. The combination with a casing, of a water propeller journaled in said casing and comprising adisk-like web having a passage therethrough, and oblique pockets on opposite sides of said web extending in opposite directions circumferentially of said web, said pockets arranged one to deliver water to said web passage and the other to direct the water from said passage.

3. The combination with a casing, of a water propeller journaled in said casing and. In testimony whereof We afiix our signacom risin r a disk-like Web havin assa es tures in resence of two Witnesses. P e a therethrough, and pockets on opposite sides THOMAS SALVESON of said Web extendin in opposite directions circumferentially of said Web, said pockets LETHA SALVESON' arranged one to deliver Water to said web Witnesses: passages and the other to dlrect the Water Mrs. S. F. ROBERTS, from ssud passages. A. J. JACKSON.
